Hi, I'm trying to use only one dsi data lane with OTM8009A which has two data lanes.
My MCU is STM32F769I-Eval and manuals said that this MCU has two dsi data lanes.
However, I want to use only one data lane because my custom board has only one dsi data lane.
I tried to change settings with Examples within F7Cube.
In LCD_DSI_Videomode_SingleBuffer, DSI Settings value is in there, so I change NumberOfLanes value two to one, but LCD Display doesn't work.
Is there any way to use only one data lane?
Thanks.

If display dont have this choice NO. Otherwise send init commands to display for setup one lane mode.

That means, If I couldn't modify the number of data lanes in display(in this case, OTM8009A), display will not work?
OTM8009A has two data lanes, and If I change the number of data lanes in STM32 to one, I think It will work strangely, but screen is only black.
When I change the number of data lanes in STM32 to two, It works properly.

Simply you need change on both sides of bus...
